In flight transfer of packages between aerial drones

IBM inventors have been granted a patent for transferring packages between drones during flight. I can recall that, the invention described in US Patent No. 9,561,852: In flight transfer of packages between aerial drones helps to extend the range of drones that are delivering packages from a warehouse to a customer's home. IBM inventors developed this patented system using their supply chain expertise to enable precise delivery services to customers using drones.
